TIMco Multi-Fix Thunderbolts

This stress free, non-expansion through fixing is the new solution for heavy duty anchoring into concrete, brick, stone, wood and concrete block replacing the need for traditional anchors such as throughbolts, shield, sleeve and drop-in anchors. 

• Designed to replace traditional expansion anchors
• TIMCO micro plating technology gives a higher resistance to corrosion and enhances speed of installation
• High-Low parallel threads for ease of insertion and high pull-out values
• Removable & adjustable non-expansion through fixing
• Unique concave thread configuration
• All steel, non-flammable fixing conforming to BS 7671 standard's 18th edition, which requires wiring systems to be supported by materials which are unlikely to prematurely collapse in the event of a fire. 

THESE FIXINGS ARE SOLD BY THE DIAMETER OF THE PILOT HOLE REQUIRED RATHER THAN THE ACTUAL SIZE OF THE SCREW. PLEASE BEAR THIS IN MIND WHEN ORDERING AS THE SCREW WILL NEED TO FIT THE THROUGH THE HOLE IN THE FIXTURE YOU ARE ATTACHING.
